Drawings are the purest and most intimate documents of how artists see, feel, and shape the world. Old paintings may well have undergone extensive restoration, so that it is hard to tell what is authentic and what is added. Even works that are undamaged may have been the work of assistants as well as the "master" of a workshop. Drawings, however, are the direct manual labour of an artist sitting there, pressing down a point against a sheet of paper. This gallery has a tremendous collection of such scintillating survivals and if you have never had the chance to visit, go, and see its tremendous permanent collection too.•Courtauld Gallery, London, from 14 June until 9 September

Masterpiece of the week

One of Titian's most powerful and troubling works, this late painting reveals the violence and danger behind the windows of Venetian palaces. Titian was the supreme painter of sensual beauty in 16th-century Venice but here he depicts a rape. This is a true masterpiece that looks as if it was painted with smoke and blood.• Fitzwilliam Museum, Cambridge
